  1. ZFS Server unerreichbar nach File Transfer

    Hallo, Mir ist heute aufgefallen, dass wenn man größere Dateien auf den FileServer (Win Server 2016 VM) überträgt, diese langsam beim Transfer beginnen und zum ende hin eine normale Geschwindigkeit erreichen. Blöderweise steigt der Server Load ebenfalls unproportional an (bis auf über 25, GUI...

  3. Proxmox ZFS UEFI Boot failure

    Hello! I was able to boot the System one time with this Topic: https://forum.proxmox.com/threads/grub2-recovery-on-zfs-proxmox-ve-3-4.21306/ I will not repair the UEFI boot due UEFI is not recommended for ZFS and Proxmox. I transfered all VMs to another Server and will reinstall the...

  7. ZFS bad Performance!

    Thanks for your Answer. It is very Helpful to know now, that it is normal that the Array performs that bad. As it is no Option for me to buy a new Server for Homelab and put 10 Disks in it, i would rather suggest to go full SSD now here, since the Prices for SSDs are low as never before. I...
  8. ZFS bad Performance!

    Alright, yes, its just a Homelab with later about 30 TB Space and various "Gaming" Servers and RDP / Terminal, Nextcloud Servers.. With Hyper V and NTFS i could use Consumer grade SSDs...

  11. ZFS bad Performance!

    Hello, Here the Output: https://pastebin.com/nG3daevg The Server is a Dell R710 with SAS Cables on the HBA. In my experience, a failure in that connection is resulting in very bad Performance, what i cant explain to myself with fio. Greetings

    The Disks are managed by ZFS, they are directly on a HBA. The Host is on the 500 GB SSD Mirror with Samsung SM883a SSDs. I just testet again, the IO delay peeks..
